STEAM -RADIATO R.

SPECIFICATION forming part of Letters Patent No. 295,700, dated March 25, 1884.

Application filed August 4, 1883. (N0 model.) i

To all whom it may concern.-

Be it known' thatI, ELISHA T. WEYMOU'IH, of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Steam-Radiators, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, and to the'letters of reference marked therein.

My invention relates especially to steamradiators employed for heating purposes, and has forits object the production of a device cheap and simple to construct, and wherein provision is made for quickly expelling the air when steam is admitted, creating a rapid circulation.

My improved radiator consists, essentially, in a base-chamber provided with inlet and outlet valves in the usual manner, in combination with a number of vertical octagonal pipes of cast metal screwed into said base, each pipe containing a circulatingtube open at both extremities, and held in place by suitable crosspieces engaging with the tube and the sides of the radiatingpipe. l The lower. extremities of the circulatingtubes extend down into the base beneath the level of the steam-inlet.

In thedrawings, Figure 1 is aview in elevation of my improved radiator, one of the pipes being shown in vertical section. Figs. 2 and 3 are views in elevation of a circulating-tube with its supporting arms detached from the radiating-pipe. Fig. 4 is a cross-sectional view of the two tubes at line at m of Fig. l.

Like letters of reference,wherever they occur, indicate corresponding parts in all the figures. n

A is the basechamber, formed of metal in the usual manner, provided with inletvalve B, outlet 0, and legs D.

E are the vertical. radiating-pipes, made preferably octagonal in form, and screwthreaded at Ffor the purpose of engaging with base A.

steam will pass up pipe E, down the circulating-tube, and through the succeeding pipes and tubes in order, the circulation taking place immediately, being unretarded by the air as is usually the case in radiators as heretofore constructed. iny device is admirably adapted to the uses and purposes for which it is intended.

Having now fully described my invention, what I claim as new therein, and desire to secure by Letters Patent, is-

1. In asteam-radiator of the character here in specified, the vertical octagonal radiatingpipes secured to a base-chamber, and having circulating-tubes, open at both extremities.

cent-rally supported by the two arms, substantially as shown and described.

It will thus be seen that 2. In a radiator of the character herein specilied. base-chamber A, having an inlet, B, and

outlet 0, octagonal radiating-pipes E, and cir culating-tubes G, centrally supported in pipes B by means of the two arms H, the said tubes being open at both extremities, as set forth, and the whole combined and arranged to operate substantially as shown and described.

In testimony that I claim the foregoing I have hereunto set my hand in the presence of two witnesses.
